The Army fleet of Tiger Armed Reconnaissance Helicopters (ARH) has been suspended from flying operations as a safety precaution.
This follows the precautionary landing of an aircraft at the Shoalwater Bay training area on 25 June, after the aircraft’s two-man crew detected fumes in the cockpit.
The aircraft landed safely with no injuries to the crew, or further damage to the aircraft.
Defence is investigating the cause of the fumes.
